The City of Cleveland has had numerous pro football teams.
The Cleveland Tigers were charter members of the American Professional Football Association, two years removed from being renamed the National Football League. This was followed by the Cleveland Indians (1931), Cleveland Bulldogs (1924-1925, 1927), Cleveland Panthers (1926) and the Cleveland Rams (1936-1945).
The Rams were born in the American Football League of 1936. Over the course of history, there have been four leagues named this, as this one is referred to as AFL2. It was an NFL-rival league with eight teams that lasted only two seasons.
